The e~cart promises quite an electrifying experience! It’s a shopping trolley re-designed to be fitted with wheels that harness the kinetic energy, generated due to its motion. The sourced up energy is deposited to the main power storage unit, when the cart docks into it. Just line them up, one behind the other to form a power chain! Although the designers suggest that the harnessed energy can be used to completely sustain the store for the month, I seriously doubt that.
Yes some amount of electricity can be generated and part of the consumption can be taken care of, but not the entire months.
